Amazon DynamoDB is a cloud database service that provides consistent performance at any scale. Hundreds of thousands of customers rely on DynamoDB for its fundamental properties: consistent performance, availability, durability, and a fully managed serverless experience. In 2022, during the Amazon Prime Day shopping event, Amazon systems -- including Alexa, the Amazon.com sites, and Amazon fulfillment centers -- made trillions of API calls to DynamoDB, peaking at 105.2 million requests per second, while experiencing high availability with single-digit millisecond performance. Reliability is essential, as even the slightest disruption can significantly impact customers.
Since the launch of DynamoDB in 2012, its design and implementation have evolved in response to our experiences operating it. The system has successfully dealt with issues related to fairness, traffic imbalance across partitions, monitoring, and automated system operations without impacting availability or performance. This talk presents our experience operating DynamoDB at massive scale and how the architecture continues to evolve to meet the ever-increasing demands of customer workloads.
